COMBlNED DECK AND DUMPING SCOW.

SPECIFICATION forming part of Letters Patent lilo.359,012, dated March 8,1887.

Serial No. 199,861. (No model.)

To all whom, it may concern:

Be it known that I, FRANKLIN 1?. EASTMAN, of the city, county, and State of New York, have invented a new and Improved Combined Deck and Dumping Scow, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved scow which can be easily changed from a deckscow into a dumpingscow, which latter is constructed in such a manner as to facilitate the unloading.

The invention consists of a scow provided with sliding hinged doors, of inclined floors leading to the sides of the hinged doors, which form either a part of the deck on each side or a peaked section in the centerof the scow, and of devices for sliding, opening, and closing the said doors.

The invention also consistsin various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar .letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of part of my improved scow, showing the same as a dumping-scow. Fig. 2 is a plan view of the same, showing the scow partly as a dumpingscow and partly as a deekscow. Fig. 3 is a vertical cross-section of the scow on the line a: 00 of Fig. 1, showing one set of side doors closed and one set of side doors open. Fig. 4c is a detail sectional elevation of one compartment with the sliding doors open. Fig. 5 is aplan view of the device for operating the sliding doors. Fig. 6 is a vertical cross section of a scow of a modified form.

The scow A is provided with the usual frame for ordinary scows, and to the frame is attached the bottom B, in the usual manner. The deck O is provided with a narrow floor, D, in the middle of the scow, and on each side of thelatter are formed the compartments E, formed by the inclined floors F, which extend from the outer bottom rail of the scow to the side edges of the floor D by the partitions G between said compartments, and by side doors, H, hinged to bars I, placed upon the upper edges of the partitions G, and sliding in suitvided with rack-teeth, which mesh into apinion, J, secured to ashaft, J, mounted to rotate in suitable bearings attached to the central floor, D. Each shaft J extends the length of one compartment, E, and operates the two pinions J, which engage the two bars I, on which the door H is hung; but two adjoining shafts, J, of a set of doors, H, on one side of the scow can be coupled together by aclutch, J of the usual construction, so as to operate two or more side doors, H, if desired.

A ratchet-wheel, J is attached to each of the shafts J, and engages a pawl, J so as to lock the pinion J' and the sliding bars I in position. The shaft J is rotated in any convenient manner. A stop'pin, 1*, is attached to each of the bars I, and rests against one of the bearings I when the sliding bar is in its innermost position, as shown in Fig. 4, so as topre vent the door H from moving outward too far.

Each door H is held in alocked position by the levers K, fulcrumed on the deck D, each lever being provided on its lower end with a hook, which engages a staple, K, fastened on the inside of the door H. A light chain, L, is attached to theinside of each door II,passes up through the compartment E, and is wound upon a drum, L, secured on ashatt,L",mounted to rotate in suitable bearings attached to the deck D, and rotated in any convenient manner. A tank, N, is formed on the lower end ofthc inclined floor F, and is provided with a pipe, N, having a stop-cock and leading to the outside of the scow.

Doors 0 are hinged to the side edges of the floor I), and can be placed over the top openings of the compartments E, resting with their outer ends 011 the upper edges of the doors H, and thereby forming adeckscow; or the doors 0 can be swung upward, so as to rest against a suitable open frame, 1?, erected on the floor D, in such a manner as to form the longitudinal peaked section Q, extending from one end of the scow to the other, in the center. I

The operation is as follows: The scow A can be used as a dumping-scow by placing the hinged doors 0 against the open frame P, so as to form the peaked section Q, as above described. The doors H are then held in a locked position, as shown in Fig. 3, by the levers K,

as shown in dotted lines in Fig. 3, by the pressure of the load against the doors. The lever K can be easily released from the staple K, as the upper end of the lever K projects into the empty space formed by the peaked section Q, and as the hook on the lever K is fixed on the lower end of the latter, it can easily be engaged or disengaged with the staple K by moving the upper end of the lever K forward or backward. The substance with which the scow is loaded can then pass out of each compartment, sliding down on the inclined floors F into the water. I11 case that the doors H do not swing open far enough, the pawls J are disengaged from their ratchet-wheels J and the shaft J is rotated,so that the pinions J, engaging the two bars I of each door H, move the latter outward until the pin 1 stops this out ward motion by coming in contact with the hearing I. The door H then assumes the position shown in Figs. 2, 3, and 4, and thus permits the complete unloading of the remainder of the load. If some of the substance to be dumped should be left on one side of the scow, the tank N on that side is filled with water from theoutsideby openingthe stop-cockin the pipe N, whereby the scow will be loaded more heavily on one side by the body of water in the tank N, thus causing the scow to hang to one side, thereby increasing the angle of the inclined floor F and the hinged door 0, so that the scow can be entirely cleared of its load. The doors H are then moved inward by revolving the shafts J in the opposite direction until they assume their former positions, and are then locked by the levers -K engaging the staples K. The chain L aids in closing the door H securely when the bars I have been run inward, so as to facilitate the locking of the levers K with the staples K. When the doors H are locked, the scow can be changed into an ordinary deck'scow by swinging the hinged doors 0 over the top opening of the compartments E, so as to form a continuous floor from side to side of the scow.

Instead of having the peaked section composed of the hinged doors, it may also be constructed of rigid inclined sides 0, securely attached to the frame-work P. I may also dispense with the sliding doors I and the means for operating the same, and hinge the doors H directly to the upper rails, A, of the scow, as shownin Fig. 6, and hold the doors in a locked position by the chain R, secured with one end to the said door and running through the compartment E upward to the central shaft, S, on which the chain is wound. The shaft S is rotated in any convenient manner, so as to open or close the door H, according to circumstances.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a dumping-scow, the longitudinal central peaked section, Q, the inclined floors-F, inclining downward and outward in the planes of the sides of the said section, and the side doors, H, in combination with the horizontally-sliding bars I, supporting the said doors H, and having rack-teeth, which mesh into the pinions J, operated by the shaft J, and the levers K, mounted on the scow and engagin g the staples K, secured to the hinged doors H, substantially as shown and described.

2. In a dumping-scow, the doors H, hinged to the horizontal sliding rack-bars I, in combination with the said bars I, the pinions J, meshing with the said rack-bars, the shafts J, on which the pinions are mounted, the ratch et-wheels J on said shafts, and the pawls J, engaging the ratchet-wheels, substantially as shown and described.

3. In a dumping-scow, the combination of the door H, the horizontal sliding rack-bar I, to which the door is hinged, operated by the pinions J, and the chain L, connected to said door and operated from the drum L on the scow, with the lever K, hooked on its lower end, so as to engage the staple K, attached to the door H, and extended upward in reach of the operator, substantially as shown and described. V

4; In a dumping-scow, the longitudinal peaked section Q, the inclined floors F, inclining downward and outward in the planes of the sides of the said section, and the compartments E, formed by the sides of the scow and the floors F, in combination with the tanks N under the inclined floors, and the pipes N, leading from the tanks to the outside of the scow and having stop-cocks, substantially as shown and described.

5. In a dumpingscow, the peaked section Q, formed by the hinged doors 0 O, the inclined floors F in the plane of the sides of said section, the side doors, H, and the compartments E, formed by said doors and floors, in combination with the rack-bars I, to which the doors Hare hinged, the pinions J, attached to the revolving shafts J, the ratchet-wheels J engaging with the pawls J* and with the rack-bars, the levers K, engaging the staples J, and extending in reach of the operator, and the chains I, connected to the doors H, operated from the drums L, substantially as shown and described.
